HOLLOW-WARE CLEANER.

SPECIFICATION forming part of Letters Patent No. 242,745, dated June 14, 1881.

Application filed February 7, 1881. (No model.)

To all whom t may concern:

Beit known that I, GILBERT BnEwsrEE, of Harvey, in the county of Albert, Province of New Brunswick, and Dominion of Canada, have invented certain new and useful Improvementsl in Apparatus for Cleansing Hollow Wares, of which thenfollowing is a specification.

My improvements relate to contrivances for cleaning the inside of bottles, lamp-chimneys,

` and other hollow wares, where the difficulty is in reaching the surface to be cleaned with a cloth or brush or other substance by which rubbing may be produced; and the nature of my invention will be apparent from the following description, taken in connection with the drawings, in which- Figure 1 shows, in section, a form of apparatusembodying my improvements, and Fig. 2 shows a cross-section ofthe stock A through the stop S.

A. is a stock or staff, which may be of wood or metal, small in diameter and round.

B is an air-tight iexiblc sack, which, as I prefer to make it, is of a thin rubber body, covered with crash or some napped or rough material, and which is made tight to the stock A at m and y, either by stretching on or winding with thread or wire, or cementing.

D is crank by which the contrivance is made to revolve'.

c is the nap or rough surface on B.

d d is a hole or air-conduit leading from near one end outside to the inside of B.

S is a stop or valve, intended to open and close the air-conduit d d', and which may be either an open-and-shut slide or a plug-cock, or, as I prefer to make it, and as shown in the drawings, a slightly-tapering cylinder, p, sliding in the stock A and having a cap, e f, at 4o either end, a perforation, g, to correspond with the hole d, and a coiled spring, s.

The operation of this contrivance is as follows: The stop S being opened to let out the air, the bag B is compressed, and the appa- 45 ratus may be easily thrust, the end afirst, into the neck of a bottle or into a lamp-chimney, for instance; then, with the thumb compressing the knob or cap c, the operator brings the holes q and d opposite, intlates B with the 5o breath, and lets go e, and the action of the spring s closes the stop S, and the air within B holds it against the sides of the hollow-ware in everypart. Then., by holding the ware with 011e hand and turning the crank D with the 55 other, the outer surface c of the bag B is Inade to revolve and operate in connection with soapsuds or other cleansing liquid.

This contrivance may be easily modified in size or proportions or arrangementof the parts 6o to suit any size or style of hollow-ware. It is cheaply made, and affords a perfect conformity ot' the rubbing or operative surface to the interiorA sides of the ware. v

I claim as new and of my invention- 65 1. A cleansing apparatus consisting ot' a stock A, an air-duct, d d', and a compressible and intlatible bag, B, constructed substanstially as and for the purposes described.

2. The combination of stock A, bag B, air- 7o duct d d', and stop S, substantially as shown and set forth.

GILBERT BREWSTER.
